Scheller, Eislingen, Fils, GermanyFiled Dec. 29, 1959, Ser. No. 862,504 Claims priority, appiicationGermany Bec. 29, 195?, 16 Claims. (Cl. 66-88) The present inventionrelates to a needle arrangement for knitting machines, and moreparticularly to a knitting machine employing a Coulier Motion andprovided with two sets of spring-hook needes for the manufacture ofvarious patterns of full-fashioned knitted fabrics.

Known knitting machines of this type are not suited for directlyconnecting a ribbed knitted fabric with a knitpurl knitted fabric.

It is one object of the present invention to improve known knittingmachines, particularly knitting machines of the Cotton type in such amanner that on the two sets of needles, either a knit-knit fabric, or aknit-purl fabric can be knitted.

Another object of the present invention is to provide a knitting machinein which a knit-purl fabric can be knitted in direct continuation of aknit-knit fabric.

Another object of the present invention is to provide a knitting machinewith additional means for operating the spring-hooks of a set ofneedles.

Another object of the present invention is to provide one set of needlesof the machine with projections on the Shanks thereof for the purpose ofspreading loops to permit passage of the needles of another set ofneedles.

A further object of the present invention is to provide a spring-hookneedle with an additional spreading projection.

With these objects in view, one embodiment of the present inventioncomprises a sinker head having a presser edge; a set of movable sinkersmounted on the sinker head above the presser edge; a set of reciprocablerst needles Ilocated below the first presser edge; a higher presser edgeylocated above the sinkers and extending parallel to the rst-mentionedpresser edge; and a set of second needles extending transverse to thesinkers and presser edges, and having spring-hooks.

The second needles are preferably movable in a vertical plane between ahigher position in which the hooks of every nth needle, preferably everysecond needle, engages the higher presser edge, and a lower position inwhich the hooks of the needles engage the lower presser edge.

Since hooks engaged by the presser edges are closed, the hooks of secondneedles closed by the higher presser edge pass outwardly of thecorresponding kinks formed in a thread formed between the sinkers andsecond needles. Thereby, corresponding horizontal rst needles receivethe corresponding thread portions for further operations.

The hooks of the second needle, not engaged by the higher presser edge,remain open to catch the other kinks of the thread and then, closed bythe lower presser edge during further downward movement, draw thecorresponding thread portions through loops suspended on the rsthorizontal needles.

Preferably, the sinker head includes a bottom part having the lowerpresser edge and a top part having the higher presser edge. The higherpresser edge is advantageously provided on a detachable rail.

The higher presser edge has preferably grooves for slidably receivingthe spring-hooks which are to be closed. Hooks which are not to beclosed, pass cutouts in the higher presser edge, so that they are notoperated.

Billl Patented Get. 31, 1.961

In the preferred embodiment of the present invention, each firsthorizontal needle has in addition to a springhook, a projection on theshank thereof which serves for spreading a 'loop on the respectiveneedle during the movement of the needle. In this manner, acorresponding second vertical needle can be moved to a position locatedbelow the spread loop so that the respective second vertical needlespasses through the spread loop on the respective first needle wherebythe loop is transferred from the rst needle to the second needle andfurther knitting operations will result in knit-purl fabric.

The spreading projections are spaced from the springhooks of the firstneedles so that the spreading projections do not interfere with theknitting of knit-knit fabric. When it is desired to stop the knitting ofthe knit-purl part of the fabric, the bar supporting the set of lirsthori- Zontal needles is shifted toward the sinker head so that thespreading projections become operative to spread the loops, and to holdthem in spread position above the ends of the vertical second needleswhich are shifted away from the sinker head into the correspondingposition to be able to pass through the spread loops on the rsthoi'izontal needles.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specic embodimentswhen read in connection with the accompanying drawings, in which:

FIG. l is a fragmentary plan View illustrating a sinker head accord-ingto the present invention cooperating with two sets of needlles;

FIG. 2 is a cross-sectional view illustrating the embodiment of FIG. 1in a first operational position;

FIG. 3 is a cross-sectional view taken on line III--III in FIG. l andillustrating another operational position;

FIG. 4 is a cross-sectional View taken on line IV-IV in FIG. l andillustrating another operational position;

FIG. 5 is a` cross-sectional view illustrating a preferred embodiment ofthe sinker head according to the present invention;

FIG. 6 is a side view of a needle in accordance with the presentinvention;

FIG. 7 is a plan v-iew of the needle shown in FIG. 6;

FIG. 8 is a fragmentary cross-sectional View illustrating an operationalposition of the needle shown in FIGS. 6 and 7;

FIG. 9 is a fragmentary cross-sectional view illustrating anotheroperational position of the needles; and

FIG. l0 is a fragmentary schematic plan view illustrating the spreadingof loops by needles illustrated in FIGS. 6 and 7.

Referring now to the drawings, 'and more particularly to FIGS. l and 2,a set of sinkers 1 is mounted in a sinker head which includes `a bottompart 2 and -a top part 3. The edge 2a of the bottom part 2 is thepresser edge for the set of vertical needles 4 which are provided withspring-hooks cooperating in a known manner with the pres-ser edge 2a.Knock-over bits 7 are located underneath the presser edge 2a of thebottom. part Z of the sinker head.

Another set of horizontal needles 5 is arranged for movement in ahorizontal plane below the bot-tom part o-f the sinker head. Needles 5have spring-hooks cooperating with the botto-m face of the presser edge2a. The sets of needles 4 and '5 are mounted in bars which are operatedby Coulier Motions to perform reciproca-ting movements in time relationto each other, and to the movements of the sinkers l.

ln accordance with the present invention, the edge 3a 3 of the top part3 of the sinker head, is` constructed as a presser edge, and is parallelto the presser edge 2a. Every second vertical needle 4 cooperates withthe upper presser edge, so that in the raised position `of the needles4, the spring-hook of every second needle 4 is closed as shown in FIGS.2 and 4.

To permit the passage of the hooks of every other needle 4 past thepresser edge 3a without closing of the hooks, the presser edge 3a isformed with cutouts 3b.

While in the illustrated embodiment the hook of every second needle 4 isclosed by the presser edge 3a, it will be understood that differentlyselected needles 4 may be operated by the presser edge 3a, so thatbroadly speaking every nth needle 4 cooperates with presser edge 3a,where n is an integer greater than one.

In the embodiment illustrated in FIGS. 1 to 4, the presser edge 3a andthe recesses 3b are provided in a fiat ledge of the top part 3 of thesinker head. In the modified construction shown in FIG. 5, an elongatedrail or bar 30 is secured to lthe top part 3 by a screw 31 and isprovided with a ledge 9 having the presser edge 3a and the cutouts 3b.

In the position illustrated in FIG. 1, the sinkers 1 are advanced, andpassing between the needles 4, have formed kinks in a thread 8 so thatthe same has a zig-Zag shape. When needles 4 are moved from the higherposition shown in FIG. 2 to the lower position shown in FIG. 4 and thenfurther down past the presser edge 2a, the hooks of those needles 4which are loca-ted opposite the projecting portions of the pressure edge3a are closed, so that the hooks pass outwardly of the kinks of thethread S, as clearly shown in FIG. 1 for every second needle 4, so thatthe respective thread portions are knocked over. The other secondneedles move down with open hooks, since they .are loca-ted opposite thecutouts 3b, and consequently catch the intermediate thread portions asshown in FIG. 1, for example, for the first needle 4 at the bottom ofFIG. 4.

The thread portions which are not caught by the hooks of needles 4 hangon the horizontal needles 5, and are formed into loops by theconventional motions of the needle 5.

vWhen needles 4 move farther down, the presser edge 2a becomes effectiveto close the hooks of needles 4, and those needles 4 which have caught athread portion of thread 8 in an open hook, draw the respective threadportion through a loop in a. conventional manner. While a knit loop, ora purl loop, is formed on a needle 4, the corresponding needle S forms apurl loop, or a knit loop, respectively. Since in the illustratedembodiment only every second loop is knocked over the point of a needle4, only every second needle 4 is associated with a horizontal needle 5,as best seen in FIG. 1. Consequently the number of needles 4 is twicethe number of needles 5 or broadly speaking n times the number ofneedles 5, 4assuming that r1 is an integer greater than 1. lf the thusknitted fabric is to be continued as a knit-purl fabric, it is necessaryto transfer the loops from needles 5 onto needles 4. In accordance withthe present invention, the needles 5 are provided with la spreadingprojection best seen in FIGS. 6 and 7. The spreading projection islocated at the center of the shank of the needle, and spaced f-rom thehook so as not to interfere with the normal knitting operations. Thespreading projection includes a spreading Wall portion 5a of triangularshape which has a less inclined edge 5b, and a more inclined edge 5c. Arectangular catch projection 5d is provided on edge 5c and extendsperpendicular to wall portion 5a. The plane in which the butt andspring-hook of the needle are located is perpendicular tothe plane inwhich the spreading wall portion 5a is located.

Referring now to FIG. 8, when it is desired to continue the knittingoperation in such `a. manner that a knit-purl fabric is made, theneedles A5 are moved toward the sinker head to such an extent that thewall 5a passes through the loop hanging on the respective needle 5 sothat the loop is spread and is held by the catch projection 5d. Thewedge-shape of the spreading wall portion Sa facilitates this operation,and the spread loop is moved by catch projection 5d into a positionlocated above the respective needle 4 which has moved to the lowerposition illustrated in FIG. 9. When the needle 4 moves upward, as shownin FIG. 9, the hook passes through the spread loop, and the loop istransferred to the respective needle 4 and in this manner, all needles 4carry loops, and when the knittinv operation is further continued, aknit-purl fabric is produced. During such further operation, the set ofneedles 5 is retracted, and does not participate in the operations.

The arrangement of the present invention in which an additional presseredge is provided for operating selected needles 4, permits the use ofidentical needles 4. This is a considerable advantage compared -withconstructions of the prior art, in which the needles have to be providedwith spring-hooks of different length.

It will be understood that each of the elements described above, or twoor more together, may also find a useful application in other types ofknitting machines differing from the types described above.

While the invention has been illustrated and described as embodied in aknitting machine including an additional presser edge, and needlesprovided with spreading projections for transferring loops, it is notintended to be limited to the details shown, since various modificationsand structural changes may be made Without departing in any way from thespirit of the present invention.

Without further analysis, the foregoing -will so fully reveal the gistof the present invention that others can by applying current knowledgereadily adapt it for various applications without omitting featuresthat, from the standpoint of prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this inventionand, therefore, such adaptations should and are intended to 'becomprehended Within the meaning and range of equivalence of thefollowing claims.
